Overnight parking area for motorhomes. Space for around 10 or more vehicles. No facilities for water or emptying.
To pay for parking you need to use the Parkingpay app (or other alternative). Once you set yourself up it is great. Note however that to enter your details, the app seems to insist that you enter a Swiss postcode as part of your address (even if you have a U.K. address). To get round this, just enter any valid Swiss postcode (eg for the tourist office or anywhere). After that you should be fine.
